Last month, Lucy had thrice as much savings as Carl. This month, Carl saves $250. As a result, he now has twice as much savings as Lucy. What is their total savings now?

3 u |
1 u |

+ $250 |
|
| After |
1x3 =
3 u |
2x3 =
6 u |
9 u |
The amount of savings that Lucy has at first and in the end remains unchanged. Make the amount of savings that Lucy has the same. LCM of 3 and 1 is 3.
Amount that Carl saved
= 6 u - 1 u
= 5 u
5 u = 250
1 u = 250 ÷ 5 = 50
Total savings now
= 3 u + 6 u
= 9 u
= 9 x 50
= $450
Answer(s): $450
